Description
M/A-COM’s MAAV-008022 is a GaAs MMIC voltage
variable absorptive attenuator in a lead-free low-cost
SOIC 8-lead surface mount plastic package. The
MAAV-008022 is ideally suited for use where linear
attenuation fine tuning and very low power
consumption are required.
Typical applications include radio, cellular, GPS
equipment and automatic gain/level control circuits.
The MAAV-008022 is fabricated with a monolithic
GaAs MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
